DPRO Passive-Infrared (PIR) PRO Series by Xtralis Planning and Commissioning Manual
If the desired detection range is not attained:
1. Slightly realign the detector upwards,
2. Repeat the walk test.
If the sensitivity is too high:
1. Reduce the sensitivity to 75% (18,30,40,45 only) or the range (PRO-51, PRO-85,
PRO-100, PRO-150) by setting DIP switch 1 to “OFF” and DIP switch 2 to “ON”,
2. Repeat the walk test.
If the sensitivity is still too high:
1. Reduce the sensitivity to 40% (18,30,40,45 only) or the range even further (PRO-51,
PRO-85, PRO-100, PRO-150) by by setting DIP switch 2 to “OFF”,
2. Repeat the walk test,
For the overall sensitivity settings of the detector set by DIP switches 1 and 2, see the
following table.
The following settings for detector sensitivity are possible with the use of DIP switches
1 and 2.
DIP-switch Status Function
1 ON Adjustable sensitivity available
only in software mode;
depending on detector model

PRO-85, PRO-100, PRO-250)
2 OFF
1 OFF 75% HW sensitivity (PRO-18,
PRO-30, PRO-40, PRO-45)
Medium HW range (PRO-51,
PRO-85, PRO-100, PRO-250)
2 ON
